A class-action lawsuit was filed against truck stop company Pilot on Friday, furthering the legal action that has stemmed from a FBI investigation into an alleged rebate fraud scheme.

The suit was filed in the U.S. District Court for the Middle District of Tennessee on behalf of Nebraska truck owner and operator Paul Otto and all other Pilot customers since Jan. 1, 2005. The class could include “hundreds, if not thousands” of members, according to the lawsuit, filed by the local office of Lieff Cabraser Heimann and Bernstein.

The suit recounts the FBI search warrant affidavit that details recordings[1] from an undercover informant of Pilot employees discussing the rebate fraud. Pilot allegedly preyed on trucking companies and customers by unknowingly reducing company rebates.
